土工布拉拔仪试验方法:

按本规定裁剪试样,试样宽度宜稍小于试验箱宽度,试样长度应使试样不被拉断,由试验确定。

每组试验应不少于3块试样。

从试验箱引出的试样端部应进行加固,试验时箱外试样不应发生很大的变形。

根据设计要求的密度和状态将试验箱下半部的土体仔细填实,填土高度与缝口齐平,平整土面。

在土面上铺放试样,拉伸端自缝口引出,注意两边对称,随即在试样上轻轻铺上一层土使试样定位。

根据设计要求的密度和状态将上半箱的土填实。

将试样的端部平整地放入拉力夹具内,对中,均匀地夹紧。

依次放上加荷顶盖和百分表,施加法向压力,固结所需时间可参照相关试验规程规定进行。

调整水平加荷装置,按下液晶显示器中文显示。依次进行试验所需测试参数。开始试验。上下箭头键为调整夹具所需位置。当拉力夹具开始受力时即为拉拔开始点。按下开始键,测读并记录位移量和水平拉力。拉拔速率可参照工试验规程,对砂性土宜取0.5mm/min。

当拉拔力出现峰值后,应继续拉拔直至拉拔力稳定,即可停止试验。

换一块试样,施加另一个法向压力,重复本节以上步骤完成全部试验

Geosynthetics puller test method:
★ Cut the sample according to this regulation. The width of the sample should be slightly smaller than the width of the test box. The length of the sample should be such that the sample is not broken and determined by the test.
★ Each group of tests should be no less than 3 samples.
★ The end of the sample taken from the test chamber should be reinforced, and the sample outside the box should not be greatly deformed during the test.
★ Carefully fill the soil in the lower part of the test box according to the density and state of the design. The filling height is flush with the seam and level the surface.
★ Place the sample on the soil surface, and draw the end from the seam. Pay attention to the symmetry of the two sides, then gently lay a layer of soil on the sample to position the sample.
★ Fill the soil of the upper half of the box according to the density and condition of the design.

★ Place the end of the sample flat into the tension clamp, centering and evenly clamping.
★ Put the top cover and the dial indicator in turn, apply the normal pressure, and the time required for consolidation can be carried out according to the relevant test procedures.
★ Adjust the horizontal loading device and press the LCD display Chinese display. The test parameters required for the test are performed in sequence. Start the test. The up and down arrow keys are used to adjust the desired position of the fixture. The pull start point is when the tension clamp begins to be stressed. Press the start button to read and record the displacement and horizontal pull. The drawing rate can be referred to the working test procedure, and it is preferable to take 0.5 mm/min for the sandy soil.
★When the pull-out force peaks, continue to pull until the pull-out force is stable, then stop the test.
★ Change one sample and apply another normal pressure. Repeat the above steps to complete all tests.
